Popular Sealco Air Valves for Trailers
Sealco makes several popular trailer valves. Go to the bottom of this page to see the Sealco valves that are currently in stock. Sealco's 110500, 110700, and 110800 spring brake valves shown below offer a choice in the quickness with which your parking brakes are released. A valve with "spring brake priority" will allow a vehicle to be put in motion sooner than a valve with "service reservoir priority".
